wondering if i'll have any problems with swapping a 2jz-ge na-t into an 92 sc400.
i have a ge tranny, ecu, and harness but im wondering if im going to have any problem with the wiring. thanks, i love u all.
(btw i almost died a few days ago, im sure you guys heard about it here in fl. )

i've always wondered this also. but i think your just going to get a lot of people telling you to try and get a sc300 instead of using your sc400....

i wouldnt think i would be any harder than a 1jz or 2jz gte swap...... just cheaper because the ge motors are cheap.

i'd do it, if i ever swapped out my 1uz and wanted power. people with sc300 are just lucky to have so much more "mod-ability" with their cars than us sc400 owners.

I have thought about this as I am trying to figure out my future engine for my 400 and there is a guy here that has done it but I can't remember his sn

i also plan on going NA-T on my SC400 early next year. Update us on your build

I'd say only if you can find an sc300 in a local yard and grab all of it- pretty much the front clip. Getting all the wiring, cluster, shifter, etc. It will make the swap far less painful. That being said, unless your SC4 is SUPER clean it's not worth it. Sell the 400 and pick up a 300.

well selling a car now-days is hard enough, just using what you got is what has to be done sometimes. imo thats 100% the case with sc400's

well i actually have a sc300 at my disposal, the frame is bent pretty bad so i need a shell. i found a super cheap 400 shell and realized that it would be better off to have the sc400 rear end (lsd). money is tight right now and i kinda have a time restriction as to getting the car up and running, this 400 is less than half the price of the cheapest sc300 i can find. im not sure about the cluster as i got hit on my driverside door pretty bad and it might have been done-in, but it wasnt in great condition anyways. once i get word that it can be done using the parts i have, im all in and will document everything for CL to use for future swaps. not to mention i have one of CL's best helping me out (seriously) with everything.
(im lucky to be alive and anyone who's seen the car/or pics will tell you that God himself is the only reason im alive, not to mention mysteriously not even a scratch!).
truth is, after seeing the true side of club lexus here in fl, i wouldnt want to have it any other way or be a part of any other community. this is more than a car community, its a family. after everything thats happened this week i can officially tell you if it wasnt for clublexus and a certain member my situation would be in shambles and my dreams of building etc would be out the window. once again i love u all

I am pretty sure sc400 does not have lsd at least my 97 does not...

I did na-t on my 93 SC400 i have a thread on here let me find it, it's not too bad specially if you have the complete swap pulled from the SC3 and going in the Sc400.
You just need to jump 3 wires at the body plugs and you are done.
You need SC3 radiator and hoses, SC300 cluster because the Rpm will 1k rpm off when the cluster says 7k rpm your are really at 6k rpm lol if you wanna keep the SC you will need to have the lines made from a hydrolic shop.

I love mine.

thanks! i guess if i get this done i'll be 1 of 2 na-t sc400's in (documented) existence lol.
so im gonna pretty much gut and drop everything over to this sc400. which lines am i gonna have to get made? im really only looking to use what i have. btw what exactly do u mean when u say "You just need to jump 3 wires at the body plugs"? sorry for the questions i just need to know what to tell my friend thats helping me with the swap so we can conveniently breeze through it.

Well being that you do have exactly what I said you would need then I say have it sir

I was talking about A/c lines if you wanna keep the A/C you will need to make the SC400 lines fit the SC300 A/C Compressor.
I didn't care about A/C on mine i removed the lines that goes to the Evaporator box.

3 wires from the Engine harness to the body plugs will need to be jump and you are up and running.

Dade305

ok. couldnt i just swap the lines from my sc300 to the sc400? its all going to the junkyard when im done anyways i might as well have a/c (mine used to be freezing cold)

Hate to bump an old thread but this is exactly what I'm in the middle of. I bought a full OBD1 GE motor and am dropping it into my OBD2 SC400.. My main concern is going OBD2 down to 1, I feel like there are going to be lots of issues with this. I will note I'm going with the GTE ECU mod and that emissions are not a concern in my state so that helps. Also, what are the 3 wires mentioned and is there anything you would do differently if you could go back and do it all over again? Any tricks or tips? Anything I should be grabbing at the salvage yard while I'm there this weekend? I already have the block, head, intake manifold, ac comp, alternator, wiring harness and GE ECU. I cant use the cluster since it's a GS nor do I want to, I love the extra little MPG things this one has.

I think the a/c lines will be the trickiest part if you are keeping that make sure to grab all that stuff off the sc3.
obd2 vs obd1 is only a few wires different that run to the obd2 connector, which you can leave. all the ecu's have the same plug 1uz and 2jzge from 92 to pretty much 97 (2 years into obd2). the body plug might need some attention but it sounds like they match up and just have to do the little wiring talked about above.

for the tt ecu mod, that is purely on the engine harness side of things, if you have an obd1 2jzge harness, you can easily do the tt ecu mod. where it plugs into the car is the body plugs which is the only thing you will have to address.

also you said gs300 motor, so you will need a rear sump oil pan setup to fit in the sc300, and probably motor mounts brackets from a sc300.
also the fusebox plugs may need some alteration between the 2 chassis they might be a little different unless you are using a sc300 engine harness then it should be more plug and play.
